Description

Technical Field

[0001] The present invention relates to the technical field of packaging box printing, and specifically to a green environmental protection printing device for packaging box printing. Background Art

[0002] In today's society, with the rapid development of industrial technology, the printing of packaging boxes has become an indispensable part of the production process. It not only concerns the external image and visual attraction of products, but also is one of the key factors for products to stand out in the market. Traditional packaging box printing technologies, such as screen printing, offset printing, and letterpress printing, although can meet the needs of industrial production to a certain extent, they have obvious defects in terms of environmental protection performance and production efficiency.

[0003] Currently, most printing equipment usually uses a conveyor belt to continuously transport packaging boxes during the printing of packaging boxes. On the conveyor belt, corresponding printing components are set to complete the printing work. However, since the printing process itself takes a certain amount of time, when the printing plate descends to print the packaging box, the conveyor belt must stop running. After the printing process ends, the conveyor belt will restart to continue its transmission work. This intermittent operation mode not only has an adverse impact on the service life of the conveyor belt, but also the frequent start and stop will reduce the printing efficiency. This reduction in efficiency not only causes waste of resources but also leads to unnecessary consumption of energy. In view of these problems, we propose a new type of green environmental protection printing device, aiming to solve the problems existing in traditional printing methods, improve printing efficiency, and at the same time reduce the impact on the environment. Summary of the Invention

DETAILED DESCRIPTION OF THE INVENTION

[0025] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Example:

[0027] Please see attached Figure 1 -Attached Figure 6 The embodiment of the present invention provides a green environmentally friendly printing device for packaging box printing, including a shell 1, a support frame 3 is fixedly connected to the outer side wall of the shell 1, the support frame 3 is used to be placed on a conveyor belt for conveying packaging boxes, the bottom center of the shell 1 is aligned with the conveyor belt, the support frame 3 is used to support the entire device, and the packaging box is printed through the internal printing component 4. A transmission component 5 is arranged inside the shell 1, and a plurality of groups of equidistantly arranged printing components 4 are arranged on the transmission component 5. The printing component 4 uses environmentally friendly ink, and the transmission component 5 drives the printing component 4 to move. When it moves to a position below the shell 1, it contacts the packaging box and moves synchronously with the packaging box to achieve uninterrupted printing, which is different from traditional ink. In comparison, environmentally friendly inks usually have a lower VOCs content, and the ink is accurately supplied according to the actual needs of the printed pattern, reducing the waste and volatilization of excess ink. The spacing of the printing components 4 is the same as the spacing of the packaging boxes on the conveyor belt. By controlling the spacing of the packaging boxes on the conveyor belt, it is adjusted to be the same as the spacing of the printing components 4 on the device to cooperate with the entire device for use. The outside of the housing 1 is fixedly connected with a drive motor 2 for driving the transmission component 5. The synchronous transmission of the drive motor 2 and the synchronous belt 51 is controlled by PLC. Through the synchronous operation of the printing component 4 and the conveyor belt, the intermittent stop of the conveyor belt during printing is avoided, which significantly improves the printing efficiency and reduces the waste of resources and energy.

[0028] The shell 1 includes a first shell 101, a second shell 102, and a third shell 103. The first shell 101 and the second shell 102 are respectively fixedly connected to the third shell 103 by welding or bolts, which plays a protective role for the entire device. The drive motor 2 is fixedly connected to the outer wall of the third shell 103. The transmission assembly 5 includes two groups of drive wheels 53. The two groups of drive wheels 53 are divided into a driving wheel and a passive wheel, wherein the central axis of the driving wheel is fixedly connected to the output shaft of the drive motor 2 and is directly driven to rotate by the drive motor 2. The central rotation of the passive wheel is connected to the inner wall of the third shell 103. The two groups of drive wheels 53 are connected by a synchronous belt 52. A connecting block 54 is fixedly connected to the inner side of the third shell 103, and the other end of the connecting block 54 is fixedly connected to a guide rail 51, which is located on the periphery of the synchronous belt 52.

[0029] The printing assembly 4 includes a slider 46 which is slidably connected to the outer wall of a guide rail 51. A connecting column 47 is fixedly connected to the outer wall of the slider 46, and the other end of the connecting column 47 is fixedly connected to the outer wall of a synchronous belt 52. Through the transmission of the synchronous belt 52, the connecting column 47 and the slider 46 can be driven to move along the track of the guide rail 51. A connecting rod 44 is rotatably connected to the outer wall of the slider 46, and the other end of the connecting rod 44 is fixedly connected to a base 43. A printing press 41 is arranged at the top of the base 43, and a printing plate 42 is arranged at the bottom of the printing press 41. The printing operation on the packaging box is carried out by bringing the printing plate 42 into contact with the packaging box. On the other side wall of the base 43, a guide block 45 is fixedly connected through the connecting rod 44. Grooves are formed in both the upper and lower parts of the guide block 45. Two groups of guide rods 48 are fixedly connected to the inner wall of the first housing 101. The guide rods 48 fit into the grooves on the guide block 45. The guide block 45 is guided by the guide rods 48 to prevent it from tilting when moving horizontally. Through the guide block and the guide rail, when the printing assembly moves horizontally, it can be ensured to be in a horizontal and stable state without lateral swing. The entire device can complete continuous printing of the packaging box by driving a motor through a PLC.

[0030] Working principle: First, place the entire device on the conveyor belt for transporting the packaging box through the support frame 3, and align the center of the bottom of the housing 1 with the conveyor belt to ensure the stability of the device and the precise alignment with the conveying path of the packaging box. The support frame 3 plays the role of supporting the entire device. When the device is ready, start the drive motor 2 fixed on the outer side wall of the third housing 103. The output shaft of the drive motor 2 drives the driving wheel in the transmission assembly 5 to rotate. Since the two driving wheels 53 (the driving wheel and the driven wheel) in the transmission assembly 5 are connected by the synchronous belt 52 in transmission, the rotation of the driving wheel will cause the synchronous belt 52 to operate accordingly. One end of the connecting column 47 in the printing assembly 4 is fixed to the outer wall of the synchronous belt 52. When the synchronous belt 52 operates, the connecting column 47 will move along with the movement of the synchronous belt 52, and then drive the slider 46 to slide on the outer wall of the guide rail 51. Since the guide rail 51 is fixed to the inside of the third housing 103 through the connecting block 54, the slider 46 can move stably along the predetermined track.

[0031] A connecting rod 44 is rotatably connected to the outer wall of the slider 46, and the other end of the connecting rod 44 is fixedly connected to a base 43. As the slider 46 moves, through the transmission of the connecting rod 44, the base 43 will also move accordingly. The printing press 41 at the top of the base 43 and the printing plate 42 at the bottom will move synchronously. When the printing plate 42 contacts the packaging box on the conveyor belt, the printing press 41 starts to work, printing the required pattern or text on the packaging box, achieving synchronous movement with the conveyor belt, so as to be able to continuously carry out printing.

[0032] On the other side wall of the base 43, a guide block 45 is fixedly connected through a connecting rod 44. Two sets of upper and lower guide rods 48 are fixedly connected to the inner wall of the first housing 101. Grooves that fit the guide rods 48 are provided at both the upper and lower ends of the guide block 45. During the movement of the printing assembly 4, the guide rods 48 will guide the guide block 45 to prevent components such as the base 43 and the printing machine 41 from tilting during horizontal movement. Moreover, the center of gravity of the entire base 43 is low. When moving to the arc of the synchronous belt 52, it will maintain a relatively horizontal state. When moving out of the arc trajectory, through the contact between the guide block 45 and the guide rods 48, the base 43 is kept moving in a horizontal state, ensuring the accuracy and stability of the printing process and guaranteeing that each packaging box can obtain a high-quality and precise printing effect.

[0033] At the same time, by controlling the spacing between the packaging boxes on the conveyor belt and adjusting it to be the same as the spacing of the printing assembly 4 on this device, continuous and efficient printing operations can be coordinated with the entire device, realizing batch green environmental protection printing production of packaging boxes and enabling uninterrupted printing.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
